Read all the statements carefully and find out which of the statements is/are sufficient to answer the given question. Choose the correct alternative for each question. A man deposited a sum of x Rs. in the bank for y year and received the amount of Rs. z. Find x : z. (A) If he had invested Rs. x at ROI of 20% per anum for y years, he would receive Rs. 600 as simple interest. (B) The value of interest obtained is 33.1% of principle invested. (C) He invested his money for 3 yearsin CI at rate of interest of 10% per annum.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Statement B: Interest = 33.1% of principal, so z = x + 0.331x = 1.331x = x : z = 1 : 1.331. This is sufficient alone. Statement C: CI at 10% for 3 years gives amount = x(1.1)³ = 1.331x, so x : z = 1 : 1.331. This is also sufficient alone. Statement A alone insufficient (only gives SI, not final amount). So either B or C alone works - answer B is correct.
